FASTENER.

Application filed January '7, 1927. Serial No. 159,688.

My invention aims to provide improvements in fasteners of the turn button type.

In the drawings, which illustrate a preferred embodiment of my invention Figure 1 is a front elevation of the complete fastener installation;

Fig. 2 is a Vertical section taken on the line 22 of Fig. 1, and being partly in elevation;

Fig. 3 is a section taken on the line 3-3 of Fig. 2;

Fig. 4. is a side elevation of the stud member;

Fig. 5 shows a lay-out of the button or head of the stud member in its form before being pressed out to form the button or head; and

Fig. 6 is a perspective view of the button or head.

Referring to the embodiment of my in vention illustrated by the drawings, the fastener comprises a turn button stud A and a grommet type of socket B adapted to be used as a fastener for securing two curtains together, or (as illustrated in Figs. 1 and 2) to secure the curtain 1 to the body 2 of a vehicle or other similar use.

The stud member has a body portion 3 formed of sheet metal pressed out to provide a base 1 and an oblong boss 5. A portion of the material forming the outer end of the boss 5 is pressed inwardly and punched out to provide an aperture 6, which is surrounded by a tapered wall 7. ending between the outer end of the boss 5 and the base 1, as shown in 2. An oblong button or head 8 is mounted upon the boss 5 for turning movement relative thereto.

The button or head 8 is pressed from sheet metal, it being first formed from a strip of metal into the shape shown in Fig. 5, and then pressed to the form shown in Fig. 6. Thus, I provide a button or head which is slit at the ends (Figs. 2 and 6) to permit a certain amount of contraction and expansion as a whole. A pair of fingers 9, 9 are formed integral with the button or head. 8 for the purpose of securing it to the body portion 3.

To assemble the parts of the stud, it is only necessary to place the button or head 8 against the outer end of the boss 5 so that the fingers 9, 9 pass through the aperture 6, and then bend the free ends of the fingggs the button or head in position.

9, 9 against the end of the wall 7, in the manner shown in Fig. 2. Thus, the body 3 and button or head 8 are resiliently secured together and the button or head 8 may be turned relative to the body portion 3.

Any form of means may be provided. for securing the stud to a support, but in this instance I have shown a screw 10 having its head 11 enclosed by the base 4 and held in nonrotatable relation, so that the stud. may be turned to turn the screw into the body 2 of the vehicle, as shown in Fig. 2.

In fasteners of the turn button type, it is preferable to have the button or head 8 held. in either one of two positions. so that it cannot be accidentally turned when in either position, the positions being that shown in Fig. 1, where the button or head 8 is turned to lock the grommet B with the stud A, or that shown in Fig. l, where the button or head 8 is shown in the position where the grommet B may be readily engaged with or disengaged from the stud A. To this end, the wall 7 forms a square aperture 6 and the fingers 9, 9 resiliently cooperate with the straight sides of the wall. Thus, when the button or head is turned from one position to another, the fingers 9. 9 turn relative to the wall 7, and as they do, they contract and then expand against the straight portions of the wall 7 to hold The resiliency of the button or head 8, acting tl'irough the fingers, is sui'licient to prevent accidental turning or rattling of the button or head 8 relative to the body portion 3.

The socket or grommet is pressed from sheet metal and has a ring-like portion 12, which seats against the outer face of the curtain 1 and a slit rivet portion 13 surrounding a stud-receiving aperture I l through the grommet B. The rivet portion. 13 passes through a hole in the curtain (Fig. 2) and the finger portions 9 of the rivet are bent outwardly against the inner face of the curtain to clench the material between them and the ring-like portion 12, as shown in Fig. 2. The aperture 14 in the grommet B is of substantially the same cross-sectional area as the cross-sectional area of the. boss 5 of the body portion 3, so that it may fit over the boss and be secured to the stud, when the button or head. 8 is turned to the position shown in Fig. l,

....1.wwwwwinwlnlnlillllilllll Aside from the fastening screw 10, the stud member is formed from only two parts, which are secured together in a simple but durable manner and provide an efiicient turn button stud which is positive in operation.

I do not wish to be limited to the particular embodiment of my invention illustrated and described.

Claims:

1. A turn button fastenercomprising a base havingan elongated boss formed thereon, an integral wall extending from the outer end of said boss toward the center of and surrounding an aperture in said boss, .a but- .ton or headdisposed upon said boss and re- :silient means integral with and extending from said button or head, said resilient means passing through said aperture and providing for resilient engagement with said Wall to secure said button or head to said boss so that one will be resiliently pressed I against the other.

2. A turn buttonfastener comprising a. base having an elongated boss formed thereon, an integral tapered wall having its free edge terminating between the ends of the boss to provide an .aperture at a point remote from the outer end of the boss, a button or head disposed upon said boss and resilient means integral witlrand extending from said button or head, said resilient means passing through said aperture and providing for r silient engagement With said wall to secure said button or head to said boss so that one will be resiliently pressed against the other.

3, A turn button fastener comprising a base having an elongated boss formed thereon, an integral wall surrounded by said boss and terminating in straight lines to provide a rectangular shapedaperture within said boss a button or head disposed upon said boss and resilient means integral with and extending from saidbutton or head, said resilient means passing through said aperture and providing for resilient engagement with said wall to secure said button or head to said boss so that one will be resiliently pressed against the other.

4:. A turn button fastener comprising a base having an elongated boss formed thereon, integral means providing for an aperture in said boss, an attaching element nonrotatably secured to said base and a turn button part mounted upon said boss and resiliently secured thereto solely by resilient projecting portions integral with said button,

ing from the outer end thereof toward said base and surrounding an aperture located internally of said boss, an elongated resilient button or head disposed upon said boss and a pair of yieldable fingers extending from said head through said aperture and engaged with the free edge of said wall to secure said button or head to said boss. said button or head being adapted to be turned relative to said boss and said wall adjacent to said aperture in said boss being rectangular in outline and said yieldable fingers co operating with said wall to hold said button or head in either of two positions relative to said boss.

6. A turn button fastener comprising a base having-an elongated boss formed thereon means providing for a square aperture in said boss, an attaching element nonroiatably secured to said base, and a resilient turn button partmountcd upon said boss and resiliently secured thereto solely by projecting portions integral with said button. said projecting portions providing combined means for resiliently securing the turn button portion in position upon said boss and means for cooperating with the peripheral wall surrounding said aperture to regulate the positions.

In testimony whereof. I have signed my name to this specification.

GUSTAV JOHNSON.
